How To Run Javascript In Visual Studio

by

Visual Studio is a popular Integrated Development Environment (IDE) developed by Microsoft, and it supports a wide range of programming languages, including JavaScript. This blog post will guide you through the process of running JavaScript in Visual Studio.

Prerequisites

Before you can run JavaScript in Visual Studio, you will need:

  • Visual Studio installed on your machine. If you don’t have it, you can download it from here.
  • Node.js installed on your machine. If you don’t have it, you can download it from here.

Creating a new project

First, we’ll create a new project in Visual Studio:

  1. Open Visual Studio.
  2. Click on File > New > Project….
  3. In the “New Project” window, select Blank Node.js Console Application, give your project a name and location, and click on OK.

Writing JavaScript code

Now we can start writing some JavaScript code. In the Solution Explorer window, double-click on app.js to open the file. Replace the default content with the following code:

console.log('Hello, World!');

This code simply outputs “Hello, World!” to the console.

Running the JavaScript code

To run the JavaScript code, follow these steps:

  1. Click on Debug in the top menu.
  2. Select Start Debugging (or press F5 on your keyboard).

Visual Studio will start a new Node.js process and execute your code. The output will be displayed in the Output window at the bottom of the screen.

Debugging JavaScript code

Visual Studio also provides powerful debugging capabilities for JavaScript code. To set a breakpoint in your code, simply click in the margin to the left of the line number. A red dot will appear, indicating a breakpoint. When you start debugging, the execution will pause at the breakpoint, allowing you to inspect variables, step through the code, and more.

Conclusion

In this blog post, we’ve shown you how to run JavaScript in Visual Studio by creating a new Node.js project, writing some simple code, and using the built-in debugging tools. With this knowledge, you can now start developing your own JavaScript projects using Visual Studio. Happy coding!
